Fixed problem in compiler optimizer with switch statement combining of different, but identical, case blocks (when reduced down to two blocks, one empty; the code compiled, but gave the wrong result).

Fixed problem in compiler with qualified enum variable used as the expression in a switch statement, without a default case (the compiler crashed in the the enum coverage check).

Fixed problem in compiler with _Bool bit-field initializers (the packed bits were converted to _Bool, which wasn't terribly useful since a nonzero _Bool value is always '1'; the code compiled, but gave the wrong result).

Fixed problem in compiler frontend with the internal 'sequence' operator, where an intrinsic function with 'side effects' (like strcpy) could have some of it's arguments killed off (the compiler crashed).

Fixed problem in the IDE with source code formatting of some C11 keywords.

Fixed problem in the IDE with C syntax coloring of "vwscanf_s", and help file association for functions following "vwscanf_s" alphabetically.
